The multi-disciplinary nature of the design of cyber-physical
systems makes it hard to gain insight in the system
behaviour early in the design process. Our aim is to allow
the designers to analyse the integration of system components
as well as the behaviour of the complete system in an early
stage. This is achieved by creating abstract component models
and refining them throughout the design process. After every
refinement cycle, the models can be co-simulated to analyse the
behaviour of the system, supporting design decisions. The co-simulation
is created based on existing standards such as HLA
and FMI and uses a domain-specific language to construct a
co-simulation automatically. This approach is illustrated using a
case study which resembles a confidential industrial case.
